Trying to get the best price on a new or used car is an uphill battle, but odds are you have some friends in your corner you didn't know about: Your credit union and your auto insurance provider.

You may already know to check with your credit union for financing on that new car, since their interest rates are likely lower than anything a bank or (heaven forbid) an auto dealer will offer you. However, credit unions also offer car buying and discount programs through selected auto dealerships that can cut hundreds—sometimes thousands—off of the sticker price of the car you want. Many car insurance providers, most notably USAA, participate in similar programs.

The folks at Kiplinger also note that select manufacturers offer discounts to credit unions and insurance companies, so sometimes it's best to start the search with the type of car you want to buy. They also suggest a free-to-join non-profit that can qualify you for a price cut. When we discussed online quoting as a way to get a good price, a few of you also mentioned that non-profits like AAA or CAA can also help you score a bargain.
